Cloud hangs startup if internet is down.

[dragon2611]

The problem

Home assistant startup hangs, I think it's a DNS resolution issue, I suspect the Home assistant container started up before pi-hole did when I rebooted the host.

"Home Assistant is starting, not everything will be available until it is finished."

Environment

• Home Assistant 0.116.4
• Docker (Debian 10 Host)
• Cloud

Problem-relevant configuration.yaml

#
# Configure a default setup of Home Assistant (frontend, api, etc)

Additional information

Restarting the Homeassitant container with no config changes worked, but ideally having DNS or internet access being unavailable shouldn't cause startup to hang.
